Abstract

Devices and systems for injecting fluids and/or other materials into a targeted anatomical location, in particular, a joint or intra-articular space, include a handpiece assembly having a needle extending from its distal end, a fluid delivery module comprising a cassette and a fluid transfer device. A conduit is generally configured to place the fluid delivery module in fluid communication with the handpiece assembly. Medicaments, formulations and/or other fluids or materials contained within vials that are secured to a cassette or other portion of the fluid delivery module can be selectively delivered into an anatomy through a needle located at the distal end of the handpiece assembly. In some embodiments, ultrasound or other imaging technologies can be used to locate a joint or other targeted anatomical location.

Claims

1. An injection system for delivering at least two different medicaments into a patient using a single needle penetration, comprising:

a fluid delivery module comprising a first loading area configured to receive a first container and a second loading area configured to receive a second container;

a handpiece assembly in fluid communication with the fluid delivery module;

wherein the handpiece assembly is configured to receive a needle assembly at a distal end of the handpiece assembly, said needle assembly comprising a needle;

wherein the handpiece assembly comprises at least one conduit that is configured to attach to the fluid delivery module, wherein when the at least one conduit is properly coupled to the fluid delivery module, the at least one conduit places the handpiece assembly and the needle assembly in fluid communication with the fluid delivery module; and

a control module comprising at least one controller, said at least one controller configured to regulate, at least in part, a transfer of at least one of the first medicament and the second medicament to the patient via the at least one conduit and the needle;

wherein the first container comprises a first medicament;

wherein the second container comprises a second medicament;

wherein the injection system is configured to receive instructions for delivering at least one of the first medicament and the second medicament through the at least one conduit and to the needle;

wherein the fluid delivery module is configured to transfer at least a portion of the first medicament from the first container to a first reservoir of the fluid delivery module;

wherein the fluid delivery module is configured to transfer at least a portion of the second medicament from the second container to a second reservoir of the fluid delivery module;

wherein the handpiece assembly is maneuverable to position the needle within the patient in order to facilitate delivery of at least one of the first medicament and the second medicament into said patient with a single penetration of said needle;

wherein, once a container is secured to the first loading area or the second loading area, said container comprises a longitudinal axis that is non-parallel with an adjacent exterior surface of the fluid delivery module.

2. The injection system of claim 1, wherein the first loading area and the second loading area are configured to receive nonspecific fluid containers.

3. The injection system of claim 1, wherein at least one of the first container and the second container is an original manufacturer'"'"'s vial.

4. The injection system of claim 1, wherein the first and second medicaments are delivered simultaneously or sequentially to a target anatomical location of the patient.

5. The injection system of claim 1, wherein the first and second loading areas and the first and second reservoirs are included in a cassette, said cassette being configured to be removably secured to the fluid delivery module.

6. The injection system of claim 5, wherein the first and second medicaments exiting the first and second reservoirs, respectively, are configured to be combined upstream of the at least one conduit and the handpiece assembly.

7. The injection system of claim 1, wherein the at least one controller comprises at least one of a button, a dial, a knob, a switch, a rollerball, a rollerwheel and a foot pedal.

8. The injection system of claim 1, wherein the fluid delivery module comprises a display, said display being configured to provide status information of an injection procedure.

9. The injection system of claim 8, wherein the status information comprises at least one of (i) a volume of the first or second medicament delivered through the handpiece assembly, and (ii) a volume remaining in the first and second reservoirs of the fluid delivery module.

10. The injection system of claim 1, wherein the fluid delivery module is in data communication with an imaging device configured to help locate a targeted anatomical location within the patient.

11. The injection system of claim 10, wherein the imaging device comprises an ultrasound device.

12. The injection system of claim 1, wherein at least of the first medicament and the second medicament comprises an anesthetic.

13. The injection system of claim 1, wherein the injection system is configured to generate a negative pressure within the needle so as to aspirate a bodily fluid of the patient at least partially through the needle when the needle is positioned with the patient.

14. An injection system for delivering at least two different medicaments into a patient using a single needle penetration, comprising:

wherein the handpiece assembly comprises at least one fluid conduit that is configured to be coupled to an outlet of the fluid delivery module, wherein, when the at least one fluid conduit is coupled to the outlet of the fluid delivery module, the at least one fluid conduit places the needle in fluid communication with the cassette; and

wherein the injection system is configured to receive instructions for delivering at least one of the first medicament and second medicament to the at least one fluid conduit;

wherein the fluid delivery module is configured to transfer at least a portion of the first medicament from the first container to a first reservoir of the fluid delivery module when a negative pressure is applied within the first reservoir;

wherein the fluid delivery module is configured to transfer at least a portion of the second medicament from the second container to a second reservoir of the fluid delivery module when a negative pressure is applied within the second reservoir;

wherein the first medicament exiting the first reservoir and the second medicament exiting the second reservoir are configured to be directed to the at least one fluid conduit when a positive pressure is applied within the first or second reservoir; and

wherein the handpiece assembly is maneuverable to position the needle within the patient.

15. The injection system of claim 14, wherein each of the first loading area and the second loading area is configured to receive nonspecific fluid containers.

16. The injection system of claim 14, wherein the fluid delivery module comprises a display, said display being configured to provide status information of an injection procedure.

17. The injection system of claim 16, wherein the status information comprises at least one of (i) a volume of the first or second medicament delivered through the handpiece assembly, and (ii) a volume remaining in the first and second reservoirs of the fluid delivery module.
